ARM: dts: aspeed: asrock: Add BIOS SPI flash chips
On e3c246d4i, e3c256d4i, romed8hm3, and spc621d8hm3 the host firmware flash is accessible to the BMC via the AST2500 SPI1 interface with an external GPIO-controlled mux switching the flash chip between the host and the BMC.
The default state of the mux GPIO leaves it connected to the host, so the BMC's attempt to bind a driver to it during its boot sequence will fail, but a write to a sysfs 'bind' file after toggling the mux GPIO (along with whatever other preparatory steps are required) can later allow it to be attached and accessed by the BMC. It's not an ideal arrangement, but in the absence of DT overlays or any other alternative it is at least a functional one, if somewhat clumsily so.

ARM: dts: aspeed: Add ASRock E3C256D4I BMC

Booting the host requires a modicum of eSPI support that's not yet in the mainline kernel, but most other basic BMC functionality is available with this device-tree.

ARM: dts: aspeed: asrock: Add BIOS SPI flash chips
On e3c246d4i, e3c256d4i, romed8hm3, and spc621d8hm3 the host firmware flash is accessible to the BMC via the AST2500 SPI1 interface with an external GPIO-controlled mux switching the flash chip between the host and the BMC.
The default state of the mux GPIO leaves it connected to the host, so the BMC's attempt to bind a driver to it during its boot sequence will fail, but a write to a sysfs 'bind' file after toggling the mux GPIO (along with whatever other preparatory steps are required) can later allow it to be attached and accessed by the BMC. It's not an ideal arrangement, but in the absence of DT overlays or any other alternative it is at least a functional one, if somewhat clumsily so.

ARM: dts: aspeed: Add ASRock E3C256D4I BMC
Like the E3C246D4I, this is a reasonably affordable off-the-shelf mini-ITX AST2500/Xeon motherboard with good potential as an OpenBMC development platform.

Like the E3C246D4I, this is a reasonably affordable off-the-shelf mini-ITX AST2500/Xeon motherboard with good potential as an OpenBMC development platform. Booting the host requires a modicum of eSPI support that's not yet in the mainline kernel, but most other basic BMC functionality is available with this device-tree.
